View corresponding 's flbgtantial ly to i zhe hne shQWIi; as prd- 70fcally slotted to receive the corresponding end of the shaft A, to whichit is riveted. The

- casting B, which is secured to the lower end of the shaft A, is ofgreater lengththan the casting B at the upper endof the shaft and has anarm 17' laterally projecting therefrom to whicheis pivotedthe operatinghandle. or lever C, the arm 17 being so disposed as to project nearlydiametrically opposite to the crank portion 15.

' The bearing brackets EE which of like construction are secured to thedoor 12 form of a-casting having an outwardly oftset central 'portion;19provided with-a slot or double'acting camgroove 20. The lower ;-keeper-D is-mountedon the door 11 adjacent the free edge'ther'eof, beingso'disprosed :and the upper keeper D is mounted on the 5 as to cooperatewiththe lower crank'arm door frame immediately above -thecdoor 11, beingso :disposed as to cooperate with; the upper-.crankarm15.

' Thedoor first closed 'is the retain the same in closed position whilethe "door operatingmechanism is manipulated, a

dthotrg h'the same :is not absolutely essential in that the operatingmechanism will proper- -ly perform'its function with the latchjmember 'Fomitted.

The handle C is adaptedto-be locked as vl'rshowninFigure 1, by anysuitable locking 7 -Qdeviceyasindicatedat 22and sealed inyany'rsuititble manner, customary onrailr'oad-cars. In operating myinvention, thedoorll Wlll ifirst'zbe movedito closed: position andsecured 7 byjthelatchFQffhe'door 12is then swung inwardly, the shaft 'Abeing first movedto ";iopposite ends of the sameiwill be disposed ingsuch a position that the crank arms 15at the az plane substantially atright anglesto the l plane' of thefdoori NVhilet'hedoor 1'2 is'ibe 1 Aiirg moved toward closed position, the 'cran'k farms 15 enter the "slots-20. After the crank door 11,.and to arms 15 have been engaged withinthe slots,

the shaft A is rotated by swingingthe handle C to the right to theposition shown in'Figure 1. Upon rotation of the shaft A, them'embers 15will be guided by the keepers D and the door 12 forced to tightly closedposition bythe crank acting oifsetoportions 15. The handle C is thenlocked to the device 22 and sealedin the usual manner. 7 p p Y To openthe door 12, thehandle G is swung outwardly away from the dooras seen inFigure 1, thereby rotating the'shaft A in the reverse direction tothatjust described. Rotation of the shaft A is continued until themembers 15 clear the slots 20, during which action the -crankp ortions15 of-the end castings B in cooperation with the grooves 20, of thekeepers will have forced the doors 11 and '12 partially apart, whereuponthe door 12 maybe swung fully open. Upon releasing the handle C, thesame-will drop out of the V waytothe dotted line position indicated inFigure 1.

From the preceding description taken in connection withthe drawing, itwill be evident that I have provided a very simple and efficient dooroperating mechanism, which entirely overcomes the defects encountered inprior devices of'this character, in that the operating shaft extendsbeyondthe top edge of the door only and hasthe'lower end thereofterminating short of the bottom of the door. a r 7.

It will be evident that my improved'door operating-mechanism isadaptedto be appliedto doors of differentdimensions varying in height, withoutmaking any changein the dimensions of the operating mechanism. In otherwords, due to the fact that the distance between the upper and lowerkeepers does not; ;in any way depend on the height; of the door, butdepends directly on ,the length of the operating shaft, the. ,dooroperating mechanism may be 'standardizedso that a single size willsuficefor all heights of,doors,-thusmaterially reducing manufacturingcosts.

I have herein shown and described wh at I now consider the preferredmanner of carry ing outmy invention but the same is merely illustrativeand I contemplateall changes andmodificatlons that come within the scopeof the claims appended hereto. ;Iicl aim: I 1
